What is a GPS exactly?

The GPS (Global Position System) or global positioning systems are satellite navigation systems that allow you to establish your position on the earth within a few meters. This is a technology that was originally created for use in the military field but expanded dramatically with multiple applications for civilian use.

The GPS positioning system works thanks to a series of land-based control stations and a network of at least 24 satellites in orbit around the Earth. For a GPS to work accurately, the device must be able to receive a signal from at least six satellites. The small GPS devices that are in many cars today are nothing more than a GPS receiver that replays the information they receive from the satellites.

What are GPSs for?

GPS devices allow you to know your exact location which makes it much easier to find your way around and arrive at a particular destination much easier. GPSs also offer you optional routes for the trips you’re making, as well as accurate information about the time of arrival and points of interest such as restaurants, shopping centres and petrol stations.

A GPS can also warn you about the presence of speed cameras, speed limit changes or specific advice such as the warning of an approaching school zone. Some advanced agricultural GPSs allow users to monitor the land of cultivation to help farmers reduce the costs of fumigation and harvesting.

What are the advantages and disadvantages of a GPS?

There are a number of important advantages as well as some disadvantages to using GPSs. With a GPS, it is possible to determine your position with a high degree of precision which allows you to establish the most efficient driving routes and estimate the approximate time of arrival. However on the contrary, a GPS can distract you from the road and increase the chances of an accident. The following table elaborates further on the advantages and disadvantages of a GPS.

Advantages Disadvantages
They let you know your position with a high level of accuracy Sometimes, they can distract you from the road and increase the risk of an accident
Some GPSs do not need to be connected to the Internet to determine your position. This way, you can use them in places where 3G or 4G internet coverage does not reach Updating maps can be an extra expense
They provide detailed information on the route and points of interest
They make it possible to estimate the approximate time of arrival
They offer information and warnings of fixed speed cameras
They help you drive more comfortably and safely, as you don’t need to rely on your mobile phones’ navigation system

Is a GPS worth buying?

If you drive regularly and do not always make the same routes, then buying a GPS is an option that you should seriously consider. A GPS can help you save time on the road as well as offer a series of “extra” information that can be very useful. If this wasn’t already enough, they can even help you avoid speeding fines.

Who should buy a GPS?

Anyone who uses a vehicle to make frequent journeys such as Uber drivers, taxi drivers, truck drivers or simply those who use their car, motorcycle or bicycle frequently. GPSs are especially useful for those who do not usually drive the same daily route.

Additionally, a GPS is particularly useful if you travel in areas where the Internet coverage is poor or there is absolutely no Internet. A GPS system is also highly recommended in the agricultural industry for farmers to track the movements of their tractors or harvesters to improve efficiency and reduces costs.

What types of GPS devices are there?

A GPS can be divided into two distinct categories: portable devices and those installed in a vehicle. The portable type can be used in different vehicles, while the built-in devices are integrated into the dashboard of the car. The following table breaks down the main features of each type.

Portable Installed
Installation They are light and easily transportable. They have a bracket to attach them to any vehicle They are normally installed as standard in the dashboard of the car
Battery You usually connect them to the car’s cigarette lighter to charge the battery on long trips You don’t have to worry about charging the battery
Speed Turn on speed varies between models. You may need to wait while the navigator system is loading They work as soon as the car is started, so the waiting time is minimal
Use They can be used in different vehicles Can only be used in the car in which they are installed
Probability of theft Given their small size, they can be easily stolen if you leave them inside the car They cannot be stolen unless your entire vehicle is stolen

What are the most important functions that a GPS usually includes?

A GPS usually includes a number of innovative and interesting features to make driving easier. Almost all models let you choose between 2D and 3D maps as well as the option of voice guidance, which means you don’t have to continuously watch the screen to know where to go. Another feature present in some GPSs is an alert system that warns drivers of an upcoming”black spots” or dangerous stretches of roads.

Another functionality available in most GPSs is the signalling of fixed speed cameras by using your location and checking against a database of known speed camera locations. GPSs also indicate points of interest and may even advise which lane is more suitable for driving.

Shopping Criteria

If you are thinking about buying a GPS, it is important that you take into account a number of different factors before making your purchase. To help you in the selection process, we have selected the criteria that we believe are the most important. We have done this with the fundamental objective of creating a shopping guide so that you can find the GPS that best suits you.

Intended use

Logically, the intended use of a GPS is one of the first questions you should ask yourself. It is essential that you take into account the type of vehicle with which you are going to use it. GPSs are usually built for use in a car, but there are also specific devices for trucks or motorcycles.

GPSs for trucks usually informs drivers about the width of the road or the height of approaching tunnels or bridges. GPSs designed for motorcycles are usually built to withstand heavy rain and have more secure brackets for attachment.

A GPS works by receiving information from at least 24 satellites that are in orbit around Earth.


When it comes to choosing a GPS, most people generally opt for one with as large a screen as possible. However keep in mind that a larger screen size usually means a higher price. In addition, the screen size isn’t the only nor the most important aspect to consider when comparing the different GPS screens.

When it comes to a GPSs screen, the resolution, the level of brightness and minimal reflection are just as important as the size of the screen. If it is not easy to see the GPS screen in sunny conditions, this can be annoying for the driver and pose an increased risk of an accident.

Some GPS models include free lifetime updates to the included maps meanwhile others require you to pay each time an update comes out. The former tends to require a higher initial economic investment, but in the long term, it may be more economical.

With this in mind, it is important to consider whether you will need new updates frequently or whether you plan on using the same regions and therefore do not need new versions. This will determine whether it is better to invest in a GPS with lifetime updates or simply pay for them as they are needed/released.

Maps included

Every GPS includes a certain level of pre-loaded maps with the device. That’s why it’s important that when choosing which device to buy, you’re clear about which package of maps you want the device to include from the start. The devices available to you will likely be different depending whether you want maps of your own state, the whole country or perhaps with the map of New Zealand. Depending on this requirement, the price will likely vary.

There are currently two main map providers for GPSs across the world: Navteq and Tele Atlas. In general, their functionalities are very similar but you may wish to analyse the points of interest they shows and the additional information that each provider includes.

It’s useful if the screen includes a night mode and even better if it is a touchscreen.


Generally, the battery of a GPS will last for two to three hours. Fortunately, charging your battery in the car is usually quite simple. If you plan on using the GPS with another type of vehicle, such as a motorcycle, where charging is not so easy, this aspect takes on greater importance.

Extra accessories

Often the attachment system of the GPS is not given much thought, but a good fastening system can save a lot of headaches. It is also essential that the GPS has a charging system that works in your vehicle. The most common form of charging is via the cigarette lighter which is reliable and easy to use.

Another interesting “extra” is a Bluetooth connection. With Bluetooth, you can usually synchronise your mobile phone with the GPS to use your phone via the GPS screen. With this extra feature you can drive much safer and more comfortably. Some GPSs also have the ability to connect to the Internet via WiFi for easy map updates.

Having a GPS can be very helpful when you are on the move. Not only to plan routes or find locations on the map, but also to know the places of interest or to warn you about upcoming speeding cameras. It’s no wonder that GPSs are so popular.

To decide which GPS is best for you, the first thing you should think about is how you are going to use it. You should also consider a series of technical specifications such as the screen, the maps included, the battery life and the “extra” accessories available.
